Background: McCune-Albright syndrome (MAS), which includes polycystic fibrous dysplasia, precocious puberty, and café au lait spots, is a rare disorder caused by somatic activating mutations of the GNAS gene. GNAS mutations have also been implicated in various sporadic tumors, including hepatobiliary and pancreatic neoplasms. Aim: The aim of this study was to assess the prevalence of hepatobiliary and pancreatic neoplasms in patients with McCune-Albright syndrome. Patients and Methods: Nineteen patients diagnosed between 1995 and 2012 with MAS in a tertiary referral center for rare growth disorders were screened with dedicated gadolinium-enhanced magnetic resonance imaging for hepatobiliary and pancreatic neoplasms between June 2011 and December 2012. Results: Six (32%) of the 19 screened patients were found to have hepatic, pancreatic, or biliary lesions, excluding liver hemangiomas, liver cysts, and focal nodular hyperplasia. This includes pancreatic ductal lesions observed in 4 patients, including numerous branch-duct intraductal papillary mucinous neoplasms in 3 patients. Biliary lesions were observed in 1 patient, with a large choledochal cyst also involving the left biliary branch. Finally, multiple inflammatory/telangiectatic hepatic adenomas were observed in 2 patients, including 1 with proven somatic GNAS mutation. Conclusion: We describe the first observation of syndromic intraductal papillary mucinous neoplasms and the new association between MAS and pancreatic neoplasms, namely intraductal papillary mucinous neoplasms of the pancreas but also rare hepatobiliary neoplasms including liver adenomas and choledochal cysts. These findings strongly suggest that somatic activating GNAS mutations, possibly through cAMP pathway disorders, are involved in the tumorigenesis of hepatobiliary and pancreatic tissues originating from the foregut endoderm and have led us to use a routine screening by dedicated magnetic resonance imaging including both pancreatobiliary and liver sequences in patients with MAS.
